摘要:
OX2 (X=halogen) molecules was studied theoretically. Calculation results show that delocalized pi(6)(3) bonds exist in their electronic structures and O atoms adopt the sp(2) type of hybridization, which violates the prediction of the valence shell electron pair repulsion theory of sp a type. Delocalization stabilization energy is proposed to measure the contribution of delocalized pi(6)(3) bond to energy decrease and proves to bring extra-stability to the molecule. These phenomena can be summarized as a kind of coordinating effect.
